I cloned an existing Samsung EVO 850 500 Gb drive with Win 10 to a new Samsung EVO 870 1Tb drive using Samsung Data Migration software. There are three partitions on the existing drive, and I cloned all three to the new drive. Using the data migration software didn't seem to present any problems as it went through the entire process and shut down when finished. I swapped the drives (this is a laptop) and when the new cloned drive boots, it shows the windows logo then a blank screen. The mouse pointer is on the screen and moves with the mouse but nothing else. No error messages or anything. The HD light flashes every couple seconds but it will just stay that way indefinitely. Any ideas as to what happened and if I need to find some other software to clone this drive.
